Copper two-socket elbow 45° VIEGA 28 mm (model 101459)

Copper two-socket elbow 45° VIEGA 28 mm is a precision-formed copper fitting intended for creating a fixed 45-degree directional change in copper piping systems. Manufactured by VIEGA, this two-socket elbow accepts 28 mm copper tubes into both ends and is designed for soldered joints, providing a durable connection for heating, potable water distribution and refrigerant lines. The fitting is suitable for professional plumbing and HVAC installations where a reliable, leak-resistant copper joint is required.

Advantages

This copper elbow is made from homogeneous copper material that ensures good thermal conductivity and corrosion resistance suitable for common plumbing and HVAC environments. The two-socket design aligns pipes for accurate soldering and simplifies assembly compared with single-fitting assemblies. Its 45° angle helps to achieve gradual direction changes that reduce flow resistance compared to sharper bends. The fitting is compatible with standard soft-soldering and brazing procedures for copper tubing and is suitable for repeated thermal cycles when installed according to best practices.

Suitable for

• Residential and commercial hot and cold water distribution
• Heating systems including radiators and underfloor heating loops
• Refrigerant and cooling lines where copper piping is specified
• Plumbing repairs and retrofits requiring a fixed 45° change of direction

Key specifications

• Material: Copper
• Connection type: Two-socket (socket ends for soldering/brazing)
• Angle: 45° fixed elbow
• Nominal tube diameter: 28 mm
• Intended joining method: Soft soldering or brazing for copper tubing
• Typical applications: Water supply, heating circuits, refrigerant lines

How to use

Prepare copper pipe ends by cutting square, deburring and cleaning the surfaces to remove oxidation and contaminants. Fit the pipes into the two sockets to the correct insertion depth. Apply appropriate flux for copper joints and perform soldering or brazing using a suitable heat source and filler material rated for the application. Allow the joint to cool naturally and inspect the soldered seam for complete capillary flow around the socket. Follow local codes and manufacturer guidelines for pressure testing and system commissioning.

Usage recommendations

Use approved flux and filler alloys for potable water or refrigerant applications, and ensure proper ventilation and safety precautions when soldering or brazing. Verify compatibility with system temperatures and working pressures and follow applicable plumbing and HVAC standards during installation.
